Air intake question bottom of first post. Pictures updated

Finally got started this week and have a few questions. First all my cook chamber is 72" x 24", my fire box is going to be 20" x 4'. I'm thinking 6" inlet pipe from firebox to cook chamber. Will all this said, how many pipes does everyone use from firebox to cook chamber? What does DP actually use? What type of air inlet on firebox? Smoke stacks, size? I'm sure I'll have more questions but this is a good start. This thing has to be cooking by July 10! I love working under pressure.

I'm thinking 5-3" holes at 6 o'clock. May be overkill but I don't have to open them up all the way. At least I'll be assured to have enough. Any thoughts?

Check out the DP site. There are plenty of photos on there that may help answer some questions. We've also got a pretty darn good sale going on right now.

I've looked at that site hundreds of times! And your right it is a good sale but some of it just have to do it ourselves! But don't get me wrong. If I had the money laying around that's exactly what I'd do but I think the misses would be less then supportive! I think she actually likes to watch me slave away in this hot Oklahoma heat.

How about a picture of the air intake on the firebox. Anybody got something like that?

I have added more pictures to the www.DiamondPlatePits.com website, but I do not have a good pic of the firebox intake. I would take one for you, but I no longer have an classic style DPP in stock. If you have a specific question, give me a call and I will be happy to help.
My phone number is on the website.

My DP Clone, made from a fuel tank, has 2- 6" pipes from the firebox to the smoker, and 2 - 4" stacks, all four are dampered. The air intake on the firebox is 3 - 3" holes at 7 o'clock on the front side of the firebox with a slider plate w/ 3 holes for adjustibility. I almost always run the air wide open and control the temps with the amount of wood.

Here's a link to a thread with a few pics-sounds like you're on the right track, you picked a great design to copy.

I have 4-4" pipes from my firebox to the cooker. Also used 2-5" truck exhaust tubes for my stacks.

I have 2-5"x5" holes for the intake...

Still working on heat regulation... Embarassed
